The 13-valent vaccine is necessary. The 13-valent pneumonia vaccine is a vaccine that covers the 13 most common serotypes of pneumococci and can prevent pneumonia, meningitis, and otitis media caused by the above pneumococci. Currently antibiotics are the main means of treating infections. The chances of cross-infection increase when babies go to kindergarten, and if babies are infected with pneumococci the treatment time is long and the cost of treatment is high, increasing the suffering of the baby and the burden on the family. Prevention is better than treatment for diseases caused by Streptococcus pneumoniae infection. Some pneumococcal infections can cause other diseases, such as myocarditis and glomerulonephritis, which can cause greater harm to children. In view of the serious threat of pneumococcal infectious diseases to children’s health, 13-valent pneumococcal vaccine has been listed by the World Health Organization as a priority vaccine for use, especially for babies with low immunity and poor health, and early vaccination is recommended.
